Literally millions of different gametes. That is why each individual is unique.
Gametes are produced by meiosis. If the male and female gametes are produced by two different individuals, sexual reproduction combines inherited
Yes. Remember that a heterozygote can produce two types of gametes. In this case, the unknown would produce gametes with the dominant allele A or the recessive allele a. The homozygous recessive would still only produce one kind gamete, with the recessive a allele. Therefore, we expect to see only two genotypes in the F1, Aa and aa, in equal proportions.
Each time a gamete is formed, one allele from each gene (i.e. either A or a) is included.This means for an individual with AaBbCc, there are 8 different gametes:ABCABcAbCAbcaBCabCaBcabc
Conifers produce gametes within their cones.
In mice the YY genotype is lethal during embryonic development. This means that the mating of heterozygous individuals will produce a ratio of 2:1 Yy to yy offspring.A 'YY' genotype is homozygous dominant for that particular trait. If it is Yy, it will be heterozygous.
sexual reproduction of genotypes
The mother will produce two types of gametes: IA and IO (mother is A) The father is AB his genotype is IAIB, thus he will produce these kind of gametes: IA and IB Four combinations are possible IA from Mother and IA from Father: The child has genotype IAIA and he has blood group A IO from Mother and IA from Father: The child has genotype IAIO and he has blood group A IA from Mother and IB from Father: The child has genotype IAIB and he has blood group AB IO from Mother and IB from Father: The child has genotype IBIO and he has blood group B Thus the phnotypic ratio is blood group A:B:AB = 2:1:1
No, However humans produce skin cells by mitosis and gametes by meiosis.
